BAG LOCK.

Application led January 12, 1924.

To all axiom t may conce/fn:

Be it known that I, DANEL E. SEDLACK, a citizen of the United States,residing at Newark, in the county of Essex and State of `New Jersey,have invented certain new and useful Improvements in Bag Locks;

and I do hereby declare the following `to be a full, clear,` and exactdescription of the invention, such as will enable others skilled in theart to which it 'appertains to make and use the same. f

The invention relates to improvements in locks for traveling bags andthe like and has for its object to provide a simple and efficient formof lock that vmay be operated only by a specific form of key, especiallyfitted to the individual lock, and thereby overcome the salientobjection to bag locks of the ordinary type, which are capable of beingoperated by a common key, and in many casesby means of a bent wire orsimilar implement, and are, therefore, of little protective value. Tothis end, the instant invention comprises a casing adapted to be securedto one of the bag frame members,` said casing ,containing` a slidinglatch cooperating with the usual hasp attachedto the other bag framemember, the latch being held normally in hasp engaging position by meansof supporting springs, and forced out of hasp engaging position by meansof a sliding finger piece which also contains a key hole, the latchcooperating with au sliding bolt provided with shoulders adapted to bemoved into and out of registry with cooperating shoulders on the latchto lock-` the same against movement, the locking and unlocking movementsof the bolt being effected by a tumbler' slidably mounted on the latch,which tumbler is associated with a catch pivoted to the latch, thetumbler and catch being provided with key engaging surfaces se disposedthatthe catch must be operated by the key Ato release the tumbler, whichlatter is then actuated by the further movement of the key to shift thebolt to either the locking o r unlocking position with respect to thelatch. By appropriately designing and arranging the key engagingsurfaces of the tumbler and the catch, it will be apparent the lock1 canbe operated only by a key provided with a special form of bit, so thateach lock will have its distinctive key and cannot ordinarily be SerialNo. 685,749.

operated by other means or other keys having differently fashioned bits.

The invention is illustrated in the accompanying drawings in which:

Fig. l is a fragmentary plan view of a traveling bag having the improvedlock applied thereto.

Fig. 2 is a side elevation of the lock viewed from the open sidethereof.

Fig. 3 is a vertical section on the line 3*?) of Fig. 2, showing thelock applied to the cooperating element of the bag frame.

F ig. 4: is a plan view of the lock with the top plate removed.

F ig. 5 is a longitudinal horizontal section through the lock. j

Fig. 6 is a perspective view of the bolt.

Fig. 7 is a perspective view of the tumbler for operating the bolt.

Fig. 8 illustrates a key adapted to operate the particular lock.

Referring to the drawings, l indicates the jaw frame member of atraveling bag to which the lock is secured and 2 the mating bag framesection which carries the usual construction of hasp 3 which cooperateswith the latch member of the lock to hold the bag in closed relation.

The lock proper comprises a casing 10 having a bottom, a; front wall andend walls, the latter being provided with the usual perforated flanges11, by means of which the casing is secured to the appropriate bag framemember by rivets, withr the `open side of the casing adjacent the flatsurface of the bag frame, as will be understood. The front wall of thecasing is provided with two spaced openings to receive the two membersof the hasp secured to the other frame member of the bag. The top of thecasing is closed by meansI of a plate 13, having'notches in its ends toreceive lugs 141e on the end walls of the casing which are bent over thetop of the plate 13 to secure the latter in. posi-y tion.

Secured to the bottom of the casing and the top plate 13 are guide pins16, located at opposite ends of the casings, and upon said guide pins isslidably mount-ed a latch 2O having hasp engaging lugs 22 struck upwarditherefrom, so as to project normally into the path of movement of thehasp members Sn?) when the latter are passed through the openings l2 inthe front wall lll) of the casing, eachi hasp member 3 having the usualopening 4 with which the correspending lug 22 cooperates. j

Formed centrally ot the top plate 13 ot the casing is a guide tia-nge17, generallyelliptical in shape, which delines theopening through whichreciprocates the usual form of hollow push button or linger piece 23 ywhich is provided on its lower portion with two leg sections 24-24,which are passed through spaced openings 21-21 in the iat body portionot' the latch 20 and upset to secure the linger piece rigidly to thelatch. The top. or' the linger piece 23 is provided with a key hole slot27, the center of which is in alignment with a key post 26 which issecured at its lower end in the bottom of the casing and extendsupwardly through the klock to a point just below the topvof the tingerpiece, so that the barrel of the operating key may be readily Vengagedwith the post and Vthe key accurately guided to its operating seat.

Secured to the ends ot the latch plate 20, by means ol lugs 3l engagingnotches 23 in the -ends of the latch plate, is an auxiliary casing 30having a bottom plate perforated to receive the guide pins 16 and thekey pin 26, said casing being cut away along its edge adjacent the frontwall of the main casing 10, the rear wallof the casing being cutaway atits mid section to provide an opening 34. Secured to the bottom of theauxiliary casing 30 are two studs or pins 35 spaced at equal distancesfrom the center ofthe casing, which serve as guides for a i tumbler 40,comprising a section stamped from sheet metal 'provided with slots 414lthrough which the pins 35 project to 'guide the tumbler in its sliding-lmovement on the bottom ot'the auxiliary casing 30. y The rear Iedge otthe tumbler has a longitudinal projection 43 which extends into theopening .in the rear wall of the casing 30 and serves as ajstop to limitthe extent of the sliding movement of the tumbler in the casing. Formed.on the Ytro-nt edge `of thel tumbler are -two spaced lugs 42-42, adaptedto` engage ythelocking bolt which will be hereinatter 4more particularlydescribed. The mid section ot the tumbler is excised, as at 44, topermit the rotation of the key and the l inner portion of the recess 44is shouldered,

'-'asat'45, to provide an engaging surface tor the lower section of thekey bit, by means of j which the tumbler is slid or'reciprocated on thebottomauxiliary casing 30. On the upper face of the tumbler, there isformed or secured an upstanding lug 46 having one vertical face rounded.

Superposed on the tumbler 40 and mounted for pivotal movement on the pin35 reymoterom the lug 46,--is a lcatch 50` having 'itsforw-ard edge-t'ormedon a curve 51, the

said curved edge being so proportioned as to cooperate with the step orprojection of the key bit immediately above theprojection on said bitwhich engages the shouldered recess 45 inthe tumbler. The forward endot' the catch 50- is forked or bifurcated to straddle the upstanding lug46 on the tumbler, and on the inner arm 52 of the fork there is 'formeda detent or projection 53 tumbler is positively held by the catch in lt-he adjustment of the tumbler to effect the unlocking lmovement ot` thebolt, thereby preventing the operationl of the latch except by means ofa specially fashioned key fitting the lock. When the tumbler occupiesits other position ot' adjustment, the lug 46 on the tumbleris inengagement with the op-k posite side of the detentv53 on the catch wit-hthe curved surface of the lug partially in engagement with the inclined.surface ot the detent, so that a sliding movement imparted to thetumbler will not be materially resisted by the engagement between thelug on the tumbler and the Vdetent on the catch, thereby materiallyfacilitating the operation ot the tumbler when the bag isbeing locked.

Secured to the pivotal end of the catch 50 is a spring 55, the other`end of which engages the-inner wall .ot the auxiliary' casing 30, saidyspring serving to swing the catch 50 on its pivot, so as to causethedetent 53 to engage the llug 46 onthe tumbler at all times, except whenthe catch is moved by the key in opposition tothe tension of the spring.The latch '20, the .linger piece 23and the auxiliary casingandthe-'elements carried'by the latter reciprocate or` slide in thecasing as a unit andware normally supported by helical springs v56Vsurrounding the guide pins 16, `sotthaltthe hasp'engaging lugs 22 ont-helatch are maintained norm-ally in the pat-h of movement of the haspmembers on the coopera-ting member ofthe bag trame. To open Athe bag, itis only necessary to depress the inger piece Q3 which forces the' latch20 and `the parts carried thereby downward until the lugs 22k pass outot 'e1ret-igeM ment with the. hasp members. When the linger vpiece4 isreleased, the latch immediateljY resumes its nor-malposition, as shownin Fig. 2, and when the bag is closed, the hasn members en gagingftherounded front-.edges of the lugs 22 torce the latch toward the bottom ofthe casingagainst the tension vof the springs 56, and. when the openingsin `the lhasp members hare .passed into registry move the latch memberupward, thereby latching the two 'javv members of the bag frame togetherin closed position, but permitting the said jaw members to be opened orseparated by merely depressing the linger piece, as will be understood.ln order to positively lock the aiv members of t-he frame together,there is provided a sliding bolt G0, which may conveniently take theform shown in Fig. 6, comprising a base section 64e slotted, as at 65,to receive the key pin Q6, a vertical yoke-like member 6l and two Wingedsections provided with upstanding lugs 62 and 63, the boltbeing'recessed or cut away on each sidel of the yoke-like section 6l toprovide openings (S6-G6 which are engaged by the lugs -l-Q on thetumbler, so that the slidin movement of the tumbler effected by theturningof the key, will produce a corresponding sliding movement of thebolt 60, such sliding movement ofthe boli; being permitted by therecessed front edge of the auxiliary casing 30. The vertical elements ofthe bolt are in sliding contact with the inner face of the fro-nt Wallof the main casing ll), so thatfivhen the bolt is moved in onedirection. the lug 62 will more into registry with a recess or notch 28formed in one end of the forward edge of `t ie latch plate 2O and thelug 63 ivill pass .into registry with the cut away front edge Q9 of thelatch plate.Y between yvhich und the inner face of the frontwall of thecasing, the yoke-like member 6l slides, and the t\vo lugs (32 and (S3will not interfere with the Dm'malsliding movement of the latch.

To lock the bag, the key. having an appropriately fashioned bit, isinserted through the key hole 27 and guided to its operating seat in thelock on the key `pin 26 which passes up into the hello-W barrel of thekey. Preferably the key hole slot is so formed that the key may beinserted with the Abit extending in either direction, as indicated inFig. l. After the key has been seated, it is given a partial turn tocause the bit to engage the front curved edge 51 of the catch 50 andswing the catch on its pivot to disengage the detent from lug l-G on thetumbler lll, permitting` the latter to be advanced by the lower elementof the key bit, which engages the shoulder el next adjacent the lug loon the tumbler', the continued` rotary movement of the key slides thetumbler along the upper surface of the bottom of the auxiliary casing30. the tumbler carrying with it, in its sliding movement, the bolt 6()until the lugs or projections 62 and G3 move ont of registry With theslotted or cut away portions 2S and 29 of the latch 2O and move directlyunder the portions of the latch adjacent the lugs 29e-22, therebypreventing any movement of the latch in the casing. The completion. oil'the locking operation v\vill leave the parts in the relative positionshown in Fig. With the catch 50, non7 free from engagement with the keybit, moved inwardly by the springso that the detent drops behind thesquared shoulder of the lug 4.6 and thereby locks the tumbler in itsadjusted position and prevents the movement of the tumbler untill thecatch 50 shall have been again swung outwardly on its pivot by the keyto disengage the detent 53 and lug 4G. W'hen it is (ilesired to unlockthe bag. the key is inserted as beforeand turned in the oppositedirection which will have the elfect of first moving' the catch 50 onits `pivot to release the detent 53 from engagement With the lug on thetumbler, the lower member of the key bit will engage the shoulderedrecess of the tumbler and move the latter and the bolt 6() in thereverse direction to bring the lugs and 63 of the bolt into registrywith the recessed or` cut away portions 2S and 29 of the latch 20, sothat the latter may be operated by the Enger piece 28, as hereinbeforedescribed. to disengage the locking lugs 22 from the hasp members 3,

TWhile the lock has been illustrated with a single catch for locking thetumbler 40, it will be obvious that a series of superposed catch membershaving the key engaging faces 5l thereof arranged in stepped oroverchanging relation to cooperate with a corresponding series of stepson the key bit, so that the several latch members ,vill have to be swungsimultaneously on the pin 35 upon which they are pivoted, to disengagethe several detents 53 on the catch members from the lugs [i6 on thetumbler s0. Ordinarily, however, a single catch will prove eective, asthe particular disposition of the key engaging surfaces of the catch andof the tumbler may be such as to adapt the lock to a relatively Widerange of keys or key bits, each lock being operable only by itsparticular key and no other.
